Peanut Butter

How to Make Guide

"The jar that holds a family together — from spoon to supper to smoothie."

A jar of peanut butter is a budget kitchen's best friend — it's protein, fat, flavor, and comfort all in one. Grandmaw always kept two jars going because running out wasn't an option when mouths needed feeding.

Garden Use a thin smear inside a homemade slug trap — they're drawn to the smell and fall into a beer-filled container

Garden Bait a mousetrap or squirrel trap with a dab — works better than cheese and doesn't spoil fast

Household Rub a small amount on a squeaky door hinge in a pinch — the oils lubricate just enough to stop the noise

Culinary Mix into rice crispy treats instead of plain marshmallow for a protein-boosted, nutty version

Culinary Spread on apple slices and top with raisins for "ants on a raft" — a snack that keeps kids full for hours

Garden Smear on a pinecone and hang outside as a bird feeder — roll in birdseed first for best results

Household Rub a few drops into dry, cracked hands in winter — the natural peanut oil moisturizes like any carrier oil

Culinary Add overnight oats ingredients straight into the empty jar — the residual PB flavors everything as it soaks

Culinary Pour in smoothie ingredients and blend with an immersion blender — gets every last bit out of the jar

Culinary Add warm vinaigrette ingredients and shake — the remaining PB turns it into a creamy peanut dressing

Garden Rinse with water and pour the peanut-water around the base of nitrogen-loving plants as a mild nutrient boost

Difficulty

Yield

About 1.5 cups from 2 cups roasted peanuts

💡 Grandmaw's Tips

🌱 Warm your peanuts in the oven at 350°F for 5 minutes before processing — warm nuts release oil faster and blend smoother.

🌱 Don't add liquid too early. The peanuts need to release their own oils first. If you add oil before they break down, you'll get gummy paste instead of creamy butter.

🌱 A good food processor is worth the investment here. A blender can work but you'll need to stop and scrape constantly, and it's hard on the motor.

🌱 Grandmaw's secret: a tiny pinch of cinnamon in homemade peanut butter makes people ask what's different. Don't tell them.

🌱 Store-bought is fine for the budget — Grandmaw won't judge. The store brand in the big jar is one of the best price-per-protein deals in the whole grocery store.

📝 Steps

1 Pour 2 cups of roasted peanuts into a food processor. Pulse 5-6 times to break them down into coarse crumbs.

2 Run the processor continuously for 1 minute. Scrape down the sides with a spatula.

3 Process another 2-3 minutes — the peanuts will go from crumbly to a ball to suddenly smooth. Be patient through the ball stage, that's normal.

4 Once smooth, add salt and honey if using. Process 30 more seconds to combine.

5 For creamier texture, drizzle in 1 tablespoon of peanut oil and process 30 more seconds.

6 Transfer to a clean jar. It'll firm up slightly as it cools. Stores at room temperature for 2-3 weeks, or in the fridge for 3 months.

7 For chunky style: remove 1/4 cup of coarsely chopped peanuts before processing, then stir them back in at the end.

Here's how to keep peanut butter all year long.

🫙 Shelf Storage (Sealed Jar)

2-3 months (homemade), 6-9 months (commercial, unopened)

Best for: Everyday spreading, cooking, baking

💡 Homemade separates faster — just stir it back together. Store the jar upside down overnight and it practically mixes itself.

❄️ Refrigeration

3-6 months (homemade), 12+ months (commercial)

Best for: Long-term storage of natural or homemade peanut butter

💡 Cold PB is hard to spread. Pull it out 15 minutes before you need it, or microwave the spoonful for 10 seconds.

🧊 Freezing

6-12 months

Best for: Bulk buying, pre-portioned smoothie packs

💡 Freeze in ice cube trays — 2 tablespoons per cube. Pop them straight into smoothies frozen. Also works great for freezing PB & J sandwiches for school lunches.

🍫 Chocolate-Dipped Freezing

2-3 months frozen

Best for: Treats, desserts, lunchbox surprises

💡 Roll PB into balls, freeze 30 minutes, then dip in melted chocolate. Back in the freezer they go. Cheaper than store-bought peanut butter cups and twice as good.

📦 Powdered Peanut Butter

12-18 months (unopened)

Best for: Smoothies, baking, lightweight camping food

💡 You can buy it powdered (PB2 or store brand) for half the calories. Grandmaw keeps a jar for smoothies and uses the real thing for everything else.
